Galvalume Corrugated Steel Sheet / Galvalume Roofing Sheet / Aluzinc Galvanized Corrugated Sheet
Galvalume (GL) corrugated steel sheet the zinc plate is used for the main elements, trace elements and add the solidification under the high temperature of 600 ℃ C and high corrosion resistance, high density of 55% aluminum-zinc silicon alloy steel plate, steel plate surface with uniform density and fine zinc/product has excellent corrosion resistance.
Galvalume (GL) corrugated steel sheet is coating consisting of of 43.4% zinc, 1.6% silicon, and 55% aluminium that performs the role of protecting metals from oxidation.Corrugated steel sheet and panels are manufactured through a cold-form process where they are pressed and roll-formed to create the desired corrugated shape. Galvalume (GL) corrugated steel sheet grooves increase the tensile strength, making it resistant to increased impact and weight loads. The steel’s corrugated configuration provides one of the highest strength-to-weight ratios of any construction material,are widely used in many industrial fields.

Galvalume Steel Sheet Advantages:
Excellent resistance to corrosion. The corrosion resistance of galvalume products is mainly associated with the protective functions of aluminium. When the zinc starts to degrade, the aluminium will form a thick alumina layer which prevents further corrosion of the materials inside. Its corrosion resistance is 3 times that of galvanized sheet.
High heat reflectivity. The thermal reflectivity of GL sheet is very high, twice that of galvanized steel sheet, and it is often used as a thermal insulation material. roofing sheet is suitable for hot climates.
Heat resistance. Galvalume steel has impressive heat resistance that will withstand temperatures that exceed 300 degrees , so it is often used in chimney pipes, ovens, luminaires, and fluorescent lampshades.
Appearance: The surface of the GL steel sheet is smooth with beautiful and uniform spangles, and the base colour is silver white, so it can be used as cladding.
GL coating has good adhesion to paint film so it can be the substrate for PPGL (pre-painted galvalume) steel.
It has good processing performance and can be punched, sheared, welded, etc. for other uses.
Store GL steel coils and sheets indoors and keep the storage area dry and ventilated. Do not store it for a long time in an acidic environment. When storing outdoors, protect from rain and avoid condensation.
